Whole Foods (WFM): Cramer said that Whole Foods reported a 3.6% increase in same-store sales from the last quarter, below the previous quarter's 4.5% rise. Moreover, that was well below other chains such as Kroger's (KR), which reported 6% same-store sales from the previous quarter.

Cramer said that given the company's ability to generate cash -- about $1 million per week per store -- the market capitalization of $9 billion was somewhat puzzling. "The opportunity is bigger than that market capitalization," he said. Cramer said that the retailer still has "enormous growth potential." The chain currently has 420 stores.

"Same store sales demonstrate organic growth," he said, and should be a good indicator of a store's performance and stock price. But he's questioning whether there may be a better methodology. He is a loyal customer. Still, he said that "the stock was not a bargain," and is "loathe to buy until we see more consistent improvement, even as I smile up to the register at my neighborhood store."

La Quinta Holdings (LQ): President and CEO Wayne Goldberg told Cramer that he was optimistic about his company's potential to continue delivering strong results and achieve growth.

The hotel chain has 870 locations and has opened new hotels in areas that it did not have a presence, including Miami, New York and Santiago, Chile. La Quinta's stock price has risen 44% since its 2014 IPO, and reached an all-time high last week. The company also beat expectations for earnings in its most recent quarter.

Goldberg said that the strong performance stemmed from the company's commitment to deliver "value to our consumers." La Quinta was among the first to include TripAdvisor (TRIP) on its individual property web sites. TripAdvisor allows customers to post reviews. "I go there and I know our consumers are there," he said. "It makes us better."

Goldberg said that attention to customer service has enabled the company to provide strong returns to investors. He said that he had "a positive outlook for the peak travel season this summer."
